    Description and History

    The ARL-99B Helldiver was conceived and designed as a labor-scale paratrooper for airborne deployment by the Japanese Air Self-Defense Forces (JASDF). Unlike early military labors (such as Hishii Heavy Industries AL-97 Atlas) the Helldiver is a much smaller, lighter and more maneuverable combat Labor. To facilitate airborne landings, the ARL-99B is equipped with a parachute sack and several landing boosters to ensure safe deployment. For attack, the Helldiver has a potent 40mm machine gun, an anti-tank missile lancher and a large, Labor-sized combat knife. The ARL-99B debuted in Patlabor Movie 1 in which several Helldivers were part of a search and destroy operation against a rogue prototype HAL X-10 Anti-Tank Labor.
